Stage 2 load-shedding will be implemented at 16:00 to 24:00 on Wednesday and at the same time on Thursday, Eskom announced. The breakdowns of a generation unit each at Duvha, Kendal and Kriel power stations during the last 24 hours, as well as the delays in returning units to service at Arnot, Kusile and Tutuka power stations have put a severe strain on the power generation system.
